悬臂式围护结构可取一单元体或单元长度进行内力分析及配筋或强度计算.悬臂式围护结构上部悬臂挡土,下部嵌入坑底下一定深度作为固定.宏观看上像是一端固定的悬臂梁,实际上二者有根本的不同之处.首先是确定不出固定端位置,因为杆件在两侧高低差土体作用下,每个截面均发生水平向位移和转角变形.其次,嵌入坑底以下部分的作用力分布很复杂,难于确定.因而企望以悬臂梁为基本结构体系,考虑杆件和土体的变形一致为条件来进行解题将是非常复杂的.现行的计算方法均采用对构件在整体失稳时的两侧和在分布做一些假设,然后简化为静定的平衡问题来进行解题.

Answer 1

Cantilever retaining structure is preferable to a unit body or unit length of internal force analysis and reinforcement or strength calculation. Cantilever retaining structure, lower upper cantilever retaining embedded under certain depth den as fixed. Macro end fixed are the cantilever beam as, in fact, there is a fundamental difference. First is sure not out the fixed end position, because of the rods in bilateral discretion under the action of soil, poor all occur every section to displacement and deformation level Angle. Secondly, embedded parts below the magnitude of the den distribution is complex, difficult to determine. Thus a cantilever beam craving for basic structure system, consider the rods and the soil deformation consistent to problem solving condition is very complicated. The current calculation methods are used to component in overall instability in the sides and make some assumptions, then distribution for the balance of the simplified statically determinate to problem solving problems.
